Remove use of router_pick_published_address() and use
relay_find_addr_to_publish instead.

Use the new relay_has_address_set() interface when deciding if we need to
fetch directory information from an authority as a relay.
If no IPv4 address is found, we'll proceed with a fetch so we can learn our
address in the HTTP header or NETINFO cell that a trusted authority will send
us back.

Tor periodic events have moved to a role base model where relays have specific
events. One of those is to rebuild the descriptor and that is ran every
minute.
This removes the call to router_rebuild_descriptor() from
router_get_my_routerinfo_with_err() because that is the only code path that
can call for a rebuild every second.
Instead, when we mark the descriptor as dirty, immediately reschedule the
descriptor check periodic event so it can be rebuilt that way instead of
randomly when router_get_my_routerinfo_with_err() is called.

When a relay builds a new descriptor, use the new relay_find_addr_to_publish()
interface to find the address to publish per family.
This commit also make the check for address consistency to also work for a
configured IPv6 for which before it was IPv4 only.

In order for a relay to find which address to publish in its descriptor,
router_pick_published_address() is used. However, that function only supports
AF_INET and uses the directory server suggested address discovery mechanism.
This new function uses a new interface so that the caller can request an
address family and get the tor_addr_t object. Furthermore, it drops the use of
directory servers address discovery (tor#33244) and instead uses the new
suggested cache that is populated at the moment from data in the NETINFO cell
coming from the directory authorities.
At this commit, function is unused.

This changes a LOT of code but in the end, behavior is the same.
Unfortunately, many functions had to be changed to accomodate but in majority
of cases, to become simpler.
Functions are also removed specifically those that were there to convert an
IPv4 as a host format to a tor_addr_t. Those are not needed anymore.
The IPv4 address field has been standardized to "ipv4_addr", the ORPort to
"ipv4_orport" (currently IPv6 uses ipv6_orport) and DirPort to "ipv4_dirport".
This is related to Sponsor 55 work that adds IPv6 support for relays and this
work is needed in order to have a common interface between IPv4 and IPv6.
Closes#40043.

Fix on unreleased code.
The relay_new_address_suggestion() is called when a NETINFO cell is received
thus not only for relay or bridges.
Remove the BUG() that made sure only in server mode we could handle the
suggested address.
Fixes#40032

We do look at the address but with this we also look if the identity digest of
the relay suggesting us an address is a trusted source.

This behaves like router_new_address_suggestion() but differs in couple of
ways:
1. It takes a tor_addr_t instead of an address string and supports both
AF_INET and AF_INET6.
2. It does _not_ use the last_guessed_ip local cache and instead only relies
on the last resolved address cache in resolve_addr.c
It is not used at this commit. This function is made to process a suggested
address found in a NETINFO cell exactly like router_new_address_suggestion()
does with the address a directory suggests us.

In practice, there will be at most one ipv4 address and ipv6 address
for now, but this code is designed to not care which address is
which until forced to do so.
This patch does not yet actually create extend_info_t objects with
multiple addresses.
Closes#34069.
Authorities currently add themselves to the trusted dir servers list,
but if they have an IPv6 ORPort, they leave it out.
This commit makes authorities add their own IPv6 ORPort to the trusted
dir servers list.
Closes ticket 32822.
This is in response to a question about why we don't always log
orport self-tests as reachability tests.
I'm not 100% convinced that bandwidth self-tests are still useful,
but that's an issue for another day. :)
Previously we had two chains of logic for reachability tests: one
for launching them, and one for telling the user that we had
launched them. Now, we simply have the launch code inform the user:
this way, we can't get out of sync.
Closes ticket 34137.
These parameters do not suppress checks, but they tell relays that
it's okay to publish even when those checks fail.
I have chosen lowercase hyphenated names, since these seem to be
more common in networkstatus params.
Closes#33224 and part of #34064.

Replace it by find_my_address() everywhere. This changes many parts of the
code that uses it to use a tor_addr_t instead of a plain uint32_t for IPv4.
Many changes to the unit test to also use the new interface.

Series of things done in this commit:
1. Rename the functions to better reflect the namespace of the file.
2. Make both reset and get function to operate on the last_resolved_addrs
cache that is per family.
3. Make the get function to take a tor_addr_t.
4. Change all callsite to use the new convention.

These identifiers are confusing and unreadable. I think these
replacements should be better. Closes ticket #40012.
This is an automated commit, generated by this command:
./scripts/maint/rename_c_identifier.py \
router_should_skip_orport_reachability_check_family router_orport_seems_reachable \
router_should_skip_dirport_reachability_check router_dirport_seems_reachable \
router_should_skip_dirport_reachability_check router_all_orports_seem_reachable
Since "skip orport check" is the "and" of v4_ok and v6_ok, we can
just compute v4_ok and v6_ok once, to clarify that we don't enter
this block of code if they're both true.
With prop312, we want to support IPv4 and IPv6 thus multiple Address statement
(up to 2) will be accepted.
For this, "Address" option becomes a LINELIST so we can properly process the
IPv4 or/and IPv6.

I've managed to keep this change mainly contained to our
self-testing module. The changes here are:
* There are two different variables for tracking "is our orport
reachable".
* We have a new function that says whether we can skip a single
family's orport reachability test; the old function for this now
tells whether we can skip _all_ orport reachability testing.
(The name, router_should_skip_orport_reachability_test, is not
so good. I will rename it later if I can think of a good
replacement.)
* The function that launches orport reachability tests now only
launches the ones that haven't completed.
* The function that notes that we're reachable on an ORPort now
takes a family.
* Various log messages are cleaned up.
